To all whom it may concern:

Be it known that I, SOLOMON A. BRAGG, a citizen-of the United States,residing at Granada, in the county of Douglas and State of Missouri,have invented a new and useful Envelop, of which the following is aspecification.

My invention relates to envelops, and has for its object to provide anenvelop of which the blank may be used as a letter-sheet and which whenfolded forms an exterior pocket or receptacle adapted for an additionalor auxiliary return-envelop.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a view of combined main and auxiliaryenvelops constructed in accordance with my invention. Fig. 2 is a viewof the main envelop, showing the rear side as seen before the auxiliaryenvelop is introduced into the pocket or receptacle provided therefor.Fig. 3 is a view of the blank from which the main envelop isconstructed, the dotted lines indicating the folding-lines and the samebeing shown perforated contiguous to one edge to adapt the blank for useas a letter-sheet which may be folded by the purchaser prior todepositing in the postoflicefor transmission, one of the securingflapsof the back fold being shown folded inwardly to expose its gummed outersurface. Fig. 4 is a View of the main envelop with the back fold foldedupon the front fold. Fig. 5 shows the auxiliary envelop arranged incontact with the back fold of the main envelop and the holding-flaps ofthe main fold arranged in their operative positions. Fig. 6 is a frontView of the envelop after the covering-flap-securin g ears have beenfolded around the ends of the receptacle and are secured to the outersurface of the front fold. Fig. 7 is a view of a blank with an auxiliaryfold perforated for the reception of coins and formed as an extension ofthe back fold, the body portion of this form of envelop being identicalwith that shown in Figs. 1 to 6, inelusive.

Similar numerals of reference indicate cor responding parts in all thefigures of the draw'- lngs.

In order that it may be understood with re gard to the direction offolding and the points of connection of the different members of theblanks, the gummed surfaces of the latter are .perform the same functionas the coveringiiap of an ordinary envelop, and 4 an aux.- iliary foldformed at the outer edge of the back fold and adapted when the parts arefolded to lie in contact with and be gummed to the inner surface of thecovering-flap, said auxiliary fold being gummed upon its inner surfaceas also is the covering-flap.

Formed at the extremities of the back fold are securing-flaps 5, alsohaving gummed surfaces which are adapted to be secured to the innersurface of the main fold 1 when the parts are arranged in the positionillustrated in Fig. 4.. WVith the parts in this position the terminalholding-flaps 6, which are formed on the main fold, are free to befolded in contact with the rear or outer surface of the back fold, andat the same time the covering-flap 3 is left free to be correspondinglyfolded in contact with the rear surface of the back fold. WVith theparts so arranged the space between the front and rear folds, andaccessible between the auxiliary fold eand the covering-flap3,constitutes a receptacle,similar to an ordinary envelop, for a letteror other object to be concealed for transmission through the mails, orby any other similar agency. It is also obvious that when the device isused as a letter-sheet the above-described folding of the rear memberupon the front member maybe accomplished, as in the ordinary practice,by the purchaser or sender of the message.

7 represents a return or auxiliary envelop of the ordinary or anypreferred construe tion, which is coextensive with the'front fold of themain envelop and is adapted to be arranged in contact with the rear orouter surface of the back fold 2, as shown in Fig. 5,

whereupon the inward folding of the holding flaps 6 and of thecovering-flap 3 will cause the engagement of the return or auxiliaryenvelop at its ends and one side edge. (See Fig. 5.) Portions of thesurfaces of the folding-flaps 6 are gummed, as shown at a, to providefor causing adhesion of said flaps to the auxiliary envelop, and therebysecuring the latter against accidental displacement during transmission.inwardly over the contiguous side edge of the return-envelop, ispreferably provided with terminal securing-ears 8, adapted to be foldedaround the ends of the front and back folds to cause their gummedsurfaces to adhere to (See covering-flap to form an exterior orauxiliary receptacle, as distinguished from the main receptacle formedby the space between the front and back folds, to receive an auxiliaryor return envelop, upon which postage is adapted to be paid at theissuing-office, and which for convenience may be marked to indicate thatsuch postage has been paid, such mark consisting of a stamped characteror any equivalent thereof which may be deemed preferable. I

The construction illustrated in Fig. 7 is exception that the auxiliaryfold (shown at 4, which corresponds with the auxiliary fold 4,ashereinbefore described, in that it is formed as an extension of the backfold 2) is preferably constructed of stiff material, as cardboard, andis provided with one or more depressions or openings 9 for the receptionof coins, said auxiliary fold being folded inwardly in contact withtheinner surface of the backfold, as indicated by dotted lines in positionillustrated in Fig. 4:, (in connection with the ordinary or commercialform of envelop.)

From the above description it will be seen that the envelop embodying myinvention may be used as a letter-sheet, in which case it is preferableto provide it near one edge The covering-flap, which is folded I with aline of perforations 10 to facilitate the removal of the end of the mainenvelop to expose its interior. Furthermore, it will be understood thatthe construction describedprovides the main envelop with an interior wtachment thereof may be accomplished with facility.

Various changes in the form, proportion, and the minor details ofconstruction maybe resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what. I

An envelop having coextensive front and rear folds, acovering-flap 3 at the outer edge of the front fold, terminalsecuring-flaps 5 on the back fold, and terminal holding-flaps 6 on thefront fold, said holding-flaps and covering-flap being overlapped andsecured to gether in contact with the rearsurface of the back fold, toform an open=sided receptacle for a separate return-envelop,substantially as specified. holding-flap, however, is to combine withthe i 2.
